TULSA, Oklahoma - A man and a woman are dead after crashing a motorcycle into a front yard in East Tulsa early Thursday morning.

The crash happened around 2 a.m. near 51st and Mingo in the Regency Park subdivision.

Tulsa Police say it appears speed and alcohol may have had something to do with the crash.

Officers say the motorcycle was headed north in the 4700 block of 93rd East Avenue when the driver failed to negotiate a curve and crashed between two parked cars in a driveway.

Lonnie Bradburry, 40, was killed instantly and his female passenger, 46-year-old Paula Kearney died a short time later, according to police.

Officers say neither Bradburry nor Kearney was wearing a helmet.  An investigation into the crash continues.
